Having some trouble getting the Amazon connector app made by Odoo to work.   Curious if anyone else has had issues or if it works perfectly for you?

Our challenge is it is not consistently bringing in the sales value.  Sometimes the sales price for a product is correct, and other times it mixes in taxes on the actual product price so the product price and totals are incorrect.  The inconsistency is what we can't figure out.  Why some work and others don't.
